Thank you Manish for quick reply. My question we have project Sales Cloud only and with going for Service Cloud licenses, can we make use of Service Cloud Feature license?

Yes we can. Same scenario is in my current project. We have service cloud licenses but we are using omni-channel skill based routing for lead in sales cloud.
